'MULE-SPINNING MACHINE.

SPEGIFICATION forming part Of Letters Patent No. 617,141, dated January 3, 1899.

Application filed April 2 6 1898.

T0 aZZ whom it may concern:

Be it known that 1, WILLIAM BoNNEY, of Linwood,in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Mule-Spinning Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to animprovement in machines known in the art as selfacting mule -spinning machines. In this class of machines the spindles on which the yarn is wound are supported on a carriage which is made to move from the head on which the drawing-rolls for drawing out the roving and delivering the same are supported and is moved inward to the head during the winding of the yarn on the spindles. In these mule-spinning machines a driving-head is placed between two spinningmachines, each consisting of a fixed frame supporting the drawing-rolls and the roving-spools and a carriage supporting the spindles. The two carriages and the spindles on the same are operated from what is termed the back shaft of the driving-head, and the two banks of drawing-rolls are operated by the rollershaft of the driving-head. The operation of these shafts is controlled by the automatic belt-shipper, which at the end of the inward traverse and at the end of the outward traverse of the carriages leads the belt from one driving-pulley to the other, and thereby re verses the mechanism by which the back 3 shaft and the roller-shaft are driven.

In mule-spinning machines as heretofore constructed (among which are what is known as the Mason mule, a mule-spinning machine built by the Mason Machine Works, of Taunton, Massachusetts) the carriage as it approaches the ends of its outward and its inward traverse controls the operation of a series of gears which operate the shipper and a rock-shaft through which the clutches connecting the back shaft and the roller-shaft are operated to connect and disconnect these shafts with the mechanism of the drivinghead. The reversing of these gears at the end of each movement of the carriage causes the same to rapidly wear, and the sudden Serial No. 678,836. (No model.)

shock in reversing frequently breaks one or more teeth in these gears, causing delay and the substitution of new gears.

The object of this invention is to simplify the mechanism of the driving-head by dispensing with the train of gears; and to this end the invention consists in the peculiar and novel construction by which the rock-shaft is operated by the carriage, as will be more fully set forth hereinafter.

Figure 1 is a side View of the frame of the driving-head, partly in section, showing my improved reversing mechanism and the operative parts of the mechanism of the drivinghead connected therewith. Fig. 2 is a top view of the same. Fig. 3 is an end view of part of the driving-head, showing the chain connection with the end cam of the rock-shaft. Fig. 4 is an end View showing the rock-shaft in section, taken on a vertical line between the end cam and the second cam to more clearly show the second cam and its chain connection. Fig. 5 is a top view of the offset bar forming the adjustable connection with the chain operating the second cam. Fig. 6 is an enlarged sectional view of the cam and clutch on the carriage-operating or rim shaft. Fig. 7 is an enlarged view of the cam, the clutch, and the operating-levers for connecting and disconnecting the roller-shaft. Fig. 8 is an enlarged view, partly in section, of the clutch mechanism for connecting and disconnecting the back shaft and Fig. 9 is an enlarged view of the cam on the rock-shaft and the lever connecting with the shipper.

Similar marks of reference indicate corresponding parts in all the figures.

In the drawings, A indicates the frame of the driving-head; B, the carriage; O, the driving-pulleys; D, the shipper; E, the rollershaft; F, the back shaft; G, the carriage-operating or rim shaft, on which the rimmed rope-pulleys are usually secured, and II the rock-shaft.

In carrying out my invention I extend the rock-shaft H, which formerly extended only to the device for. operating the clutch on the roller-shaft, to the front end of the drivinghead and secure to the same the cams 10 and 11 close together at the other end of the driving-head. At a point below the roller-shaft E, I secure the cam 12 to the rock-shaft II,

which on the partial rotation of the rock-shaft acts on the clutch-lever 13 to move the clutch 14, which is connected with the roller-shaft E by a groove and spline, and disengage the same from the clutch 15, which is constantly driven, but is secured to a sleeve loose on the roller-shaft E, so that when the parts 14 and 15 are in engagement the roller-shaft is rotated and when detached the roller-shaft E remains stationary. The coiled spring 16 holds the half-clutch 14 in engagement with the driven half 15 of the clutch until the cam 12 acts on the clutch-lever 13 to disengage the clutch and the roller-shaft E from the con stantly-driven half 15 of the clutch. The cam 17, secured to the rock-shaft H, engages With the pivoted lever 18, having 011 its opposite end the set-screws 19 19, which bear on the end of the shipper-lever 20, the opposite end of which engages with the clutch 21, connected with the back shaft F by a groove and spline, so as to rotate with the same and permit of the sliding of the clutch 28 longitudinally on the back shaft. Then the clutch 21 is connected with the gear 22, the gear rotates the back shaft, and when disconnected the gear 22 rotates on the back shaft without turning the same.

The cam 23 on the rock-shaft H cooperates, as is shown in Fig. 9,with the lever 24, secured to the shaft 25, on which the shipper-arm 26 is pivotally supported, whereby the shipper is operated by the partial rotation of the rockshaft H, the rotation of which is controlled by the carriage B. On the side of the carriage toward the roller-beam the bracket 27 is secured, and on the brackets a pin is adjustably supported. As is shown in Fig. 2, the spring shipper-bar 29 is secured at one end to the post 30. The opposite end of the shipper-bar 29 is forked and engages with the clutch 31, which is connected, as shown in Fig. 6, with the rim-shaft G by a groove-andspline connection, so as to rotate with the same. roller-beam the pin 28 bears on the inclined surface of the spring shipper-bar and moves the clutch 31 into engagement with the clutch end of the cam 31 and causes the same to rotate with the rim-shaft G. One end of the chain 32 is secured to the cam 31 and the other end to the rod 33, sliding in suitable bearings and provided with the coiled spring 33, the tension of which may be regulated by the adjustment of the usual form of a stop against which one end of the coiled spring bears. To the screw-threaded end of the rod 33 the offset bar 34 is adjustably secured, and from the end of the offset bar 34 extends the chain 35, passing under the pulley 36. The end of the chain 35 is secured to the cam 11 on the rock-shaft H. On the outer side of the carriage B the roller 37 is supported in a suitable bracket secured to the carriage and cooperates with the lever 38, one end of which is pivotally supported on the post 39. The chain 40 is secured at one end of the lever 38 As the carriage B approaches the the clutch 31 into engagement with the cam 31, which, turning with the shaft G, exerts a strain on the chain 32, which is transmitted to the chain 35, connected to the cam 11, secured to the rock-shaft H, and turns the same through one-half of a revolution into the position shown in Fig. 4. The cam 10, also se cured to the shaft H and connected by the chain 40 with the lever 38, operates the lever 38 and raises the same into the position shown in broken lines in Fig. 1. The rotation of the rock-shaft H is limited to half a turn by the stop-pins 10 10 on the cam 10 coming into contact with the brackets 10*. One of these pins is longer than the other and has the end of the coiled spring 10 secured to it, the other end of the spring being secured to the frame A, as is shown in Fig.3. The spring 10 is shown holding one pin 10 against the top of the bracket 10 when the shaft is turned. As soon as the pin 10 to which the spring is connected passes the center the strain of the spring carries the other pin 10 into contact with the lower side of the bracket 10 and limits the rotation of the shaft H. As the carriage backs off as soon as it reaches the inward traverse the spring shipper-bar 29 by its resiliency moves the clutch 31 out of engagement with the cam 31, and this cam by its own weight and the weight of the chain returns to the position shown in Fig. 1. When the carriage approaches the outward end of its traverse, the roller 37 encounters the inclined cam 38 of the lever 38 and depresses the same, the chain 40 rotating the cam 10 sufficient to cause the spring 10 to complete the rotation through half a revolution and bring the pin 10 against the bracket 10 The turning of the rock-shaft by one chain takes up the slack and places the other chain in its operative position, and the complete turning through half a revolution of the cams 10 and 11, as well as of the cams 12, 17, and 23, is insured by the spring 10 the pins 10 10, and the brackets 10 thereby insuring the prompt movement of the back-shaft and roller-shaft clutches and the movement of the shipper without the use of the train of gears heretofore required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a mule-spinning machine, the combination with the carriage, and means for reciprocating the same, the roller-shaft, the back shaft, the shipper and the usual rockshaft, of an extension of the rock-shaft, two

cams secured to the extension of the rocktrolled by the carriage, for alternately rock- 15 ing the rock-shaft in opposite directions, and cams on the rock-shaft operating the clutches on the rollershaft and back shaft, and the shipper; Wherebythe machine is reversed at each end of the reciprocation of the carriage 20 through the partial rotation of the rock-shaft controlled by the carriage, as described.

In witness whereof I have hereunto set my hand.
